What is the description of Twilight?

Being a fellow Twi-hard, i can answer this.

Bella Swan moves to Forks, WA to live with her father. While in school, she is paired up with Edward Cullen as her Biology partner. He becomes very protective of her and shows up where ever she is. He tells her that he is vampire. She instantly falls for him. Now its up to the Cullen family to keep Bella protected from the nomadic vampires. She is the only human to know there're vampires existing.

Hope this helps :)
